Wire applying forceps



-ing and wrapping hand tool devices.

Patented Dec. 7, 1948 "um-m) TESQPAT This invention relates to linetensioning;

This invention hasyutilityywhen incorporated in a pivoted member pairstructure, especially adapted" to clamp engage ,awire, upon oppositesides of an intermediate portion tobe actedupon. This intermediateportionmay bea loop, say as a wrap about a bone fracture, in surgical,use. The wire portions as extending from the initial wrap, are clampedindependently, one in each of the two relatively movable or spreadablejaw portions. The jaws may then be spread to put an opening tension onthe crossed ends of the wire. With this position locked at the handleportion, the handles may then be turned to twist the wire into the moretaut desired final holding position therefor.

Referring to the drawings: I Fig. 1 is a side elevation of an embodimento the invention at assembled position for a wrap at a bone fracture;

Fig. 2 is an end elevation of one of the wire holder engaging membersorjaws;

Fig. 3 is an enlarged view in side elevation of the tensioning or spreadposition of the wire end engaging portions as locked for the twistingstage to start; and

Fig. 4 is a fragmentary plan view of a Wire end holding clamp mounted ona wire end engaging arm of the tool.

Fractured bone sections I, 2, about marrow 3, have a line or wire 4 wrapwith crossed diverging wire portions 5, 6, therefrom. The wire portion 6enters a port I in a face 8 of a. wire engaging jaw or spread portion 9as an arm of a member having a fulcrum at a pivotal connection I with ahandle portion or grip II. Complementary to the portion 9 is aspreadportion I2 of the companion member of the tool extending past thecommon pivotal connection In to an additional handle portion I3, whichwith the portion I2 are assembled as a grip, adapted for twisting orturning in wrench-like action.

The wire end 6 as passing thru the port I passes along the outer sideofthe portion'9 as away from the portion I2 as a taut straight section 14having a bend or hump I to free end I6. Upstanding lugs or pins IT, IS,determine the sides for the bend I5 as an arc about a screw stem I9 inthe member arm 9 midway between 1 mm. (011 123+ I twi Thethreaddirection bf thae I9, say as m de wisein Fig. 4, meansthattensioning pull "of the section I4 toward the port I, is in theturningdirection forthe stem I9 to more tightly'clamp and holdthe wire at thehump I5. The, spread arm portion ,I2, has thru its free endlport fromthe wire, portion 5 a straight, section 22, similar to the portion I I.The portion 22 ,extendstoa Wire clamp device 23,1similar to thedevicehaving thehnurledhead 2I Likewisehere, clockwise turning of thedevice 23"is to efiect wire clamping, with a hump about astem 24, in itspull direction from the wire portion 5, eifecting more firm binding atthe device 23.

The handle portion I3 near its free end has fixed therewith an archedspring strap 25 with its free end 26 to ride in a slideway 21 along theinner side of the handle portion II. There is thus provided yieldablemeans normally closing the jaws 9, I2. A pivot 29 in the handle portionI3 spaced from the hinge or pivot connection I0 away from the clampdevices 2|, 23, has rockable clearance 29 for a threaded stem 30extending from the pivot 28 thru a slot 3I in the companion handleportion II, there to be engaged by a knurled nut 32. Setting of this nut32 to flex the spring 25, acts to spread the jaws 9, I2, and therebytension initially the cross reaches 5, 6, of the wire. As so locked bythe nut 32, the handle pair unit II, I3, may be readily twirled intwisting the clamped-ended Wire in bending I the cross portions 5, 6,upon each other to the desired binding extent.

What is claimed and it is desired to secure by Letters Patent is:

1. For initiating and adjusting a line loop to a desired completion, atwo member tool body, a pivot connection between the members for themembers to provide diverging handle portions I portion remote from theconnection and having the small posts or lugs I1, I9. The screw stern abow portion therefrom to a free end having a slide connection with theadjacent side of the other handle portion and thereby to coact to spreadthe handle portions and cause the jaw edges to approach abuttingrelation, an adjusting device coacting between the handle sections tolimit the effective spread action of the spring,

there being on each jawv spaced from the port,

a flat seat for a hump of a reach of the line from the loop to lodgeflatwise thereagainst, and a clamp to pinch the flat portion of the humptoward the seat and thereby effecting each direction locking of theline.

2. A spread type surgical two member tool, a pivot connection betweenthe members for the members to provideapair of opposing jaw portions oneway from the connection and, the other way therefrom, a pair ofdiverging handle portions adapted as grasped to spread the jaw portions,each jaw having fixed therewith a line clamping seat, whereby graspingof thehandles to move them toward each other holds the line,

clamped portions taut, a handle-portion spreading spring coactingdirectly between the handle portions remote from the connection, and,toward.

the connection from the spring, adjusting means directly engaging thehandle to limitthe spread extent of the spring and thereby determine. aheld "spacing for the jaw portions, whereby the tool may be set toholdthe line tensioning for the line having opposite line portionsengaged by the jaw portions.

'3. A hand tool for forming. a line loop, said tool comprising a pair ofmembers, a. pivot connection between the members for the members toprovide diverging handle. portions extending one way from the connectionand jaw portions the other way from the connection, each jaw portionouter side near the connection having a pair of posts with a flat seattherebetween, and a clamp screw to press a line hump arced about thescrew and within the posts to be pressed against said seat to lock theline against thrust and pull disturbance.
